Using 600W on 550W power supply.

[,,,,,,,,,,,,,,,,,,,,,,,,,,]

Check out my system using 600W on my EVGA 550W EVGA G2.

 

Specs:

 

7700K

980ti

1070

 

Running unraid.

 

The plan was to run 970s - that is why the PSU is only 550W. Normal gaming usage is 450 - 500W.

Its probably fine, its of good quality and it will most likely shut down before taking damage if the strain becomes to much.

A 550w PSU can deliver 550w (continuously) to the components. Now, since it has an efficiency around 85-90% under 100% load, that means you'll be drawing up to 650w from the wall. It's perfectly normal, don't worry about it.

Yeah, not too worried about it. I have an 850W, but I'll leave this in until it dies.

Well the load tester thingy that reads out wattage doesn't account for efficiency. If you were demanding all 550W from the G2 you'd be drawing roughly 632W from the wall so you've still got like 20W-ish headroom

A g2 is very high quality, you might already move on from 970 sli when it happens lol

The 550W number on your power supply is it's output, not power draw from the wall.  If it was 100% efficient (it's not) the output would be equal to the power draw from the wall.

 

If the power supply is 90% efficient, you're putting out 549W when you're pulling 611 from the wall.
